Answer:
Diameter of a hemisphere: d = 2 * r ,
Volume of a hemisphere: V = 2/3 * π * r³ ,
Base surface area of a hemisphere: Ab = π * r² ,
Cap surface area of a hemisphere: Ac = 2 * π * r² ,
Total surface area of a hemisphere: A = 3 * π * r² ,
We know that for a hemisphere whose radius is 9 units, The volume is: Volume of hemisphere=2πr33 Volume of hemisphere = 2 π r 3 3
Step-by-step explanation:
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
Answer:
isosceles
Step-by-step explanation:
as isosceles has two sides equal meaning two angles equal
Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a horizontal quadratic function, of vertex (h,k), is given by:
(y - k)^2 = 4p(x - h)
The directrix is given by:
x = h - p.
In this problem, the equation is given by:
(y - 2)² = 0.25(x - 5).
Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:
x = h - p = 5 - 0.0625 = 4.9375.

Answer:
-3p+6p=3p
Step-by-step explanation:
It's just like saying -3+6,
but just with the p.
-3+6=3
therefore the answer is 3p
